posting photos to the right side widgets column on my blog

I'm trying to put a picture of myself in the right column of my blog Alwaysbejobhunting.com, with the various widgets but can't find a way to do that, I've tried the photo one but it asks for a web address, is there no way to load a photo I have on the site into that side column? Also, I want to put a link there to my book on amazon and so far have only been able to put a small one, I want one that includes a picture of the book cover, is that possible?

I suggest you create a draft post and do all your work in it. Once everything is proper then switch to the HTML editor and copy the code. Open a text widget and paste the code into it. Then check the diaply. If everytjing is fine you can delete the draft post. http://en.support.wordpress.com/links/text-widget-links/
